So, is a Ghost immobiliser worth it? For most keyless cars, vans and pickups, yes. Today, few thieves smash a window and hot-wire a car. Instead, they copy the key signal or program a new key, then simply drive away.
A Ghost immobiliser stops that. Before the engine will start, it asks for a PIN code, entered on buttons your car already has. So a copied or relayed key is not enough on its own. However, Ghost is not the full answer for every car. Below, we explain what it stops, what it can’t, and who should fit one.
We fit Ghost immobilisers in our Cardiff workshop, and customers come from Penarth, Barry, Newport and across South Wales. So this guide is what we tell people at the counter, written down.
What a Ghost Immobiliser Actually Does
- It blocks the engine until your personal PIN code is entered.
- You enter the code on your car’s own buttons, such as the steering wheel or window switches.
- Ghost-III also offers an optional key-tag or phone app, with the button code kept as a backup.
- There is no fob to lose and no LED, so a thief can’t spot it from outside.
- It talks to the car through its data network, so no factory wires are cut.
- It re-arms itself every time, so you never forget to set it.
| Current model | Autowatch Ghost-III, which replaces Ghost 2 |
| Approval | TASSA approved. Ghost is not a Thatcham product |
| How you disarm | PIN on factory buttons, or optional key-tag or app |
| What it stops | The car being started and driven away |
| Visible parts | None. No fob, no LED |
| Factory wiring | Not cut, so your warranty is unaffected |
| Garage visits | Service and valet mode, so you keep your PIN private |
| Newer cars | Ghost-III supports CAN-FD networks |
The newest version is the Autowatch Ghost-III. In fact, Autowatch says older units, including Ghost-II, do not support the faster CAN-FD networks in many new cars. That’s why we now fit Ghost-III. Your existing Ghost 2 keeps working, though.
How Thieves Steal Cars Now, and Where Ghost Fits In
First, it helps to know how modern car theft works. In fact, many modern thefts involve no broken glass at all. Instead, thieves use electronics, and they are quick.
Relay Theft
With keyless entry, your car unlocks when the key is close. So thieves use a pair of devices to pass the key’s signal from your house to the car. The car thinks the key is there. Then it opens and starts.
Key Cloning and Key Programming
Next, some thieves plug into the diagnostic port under the dash. From there, they can program a blank key to the car in minutes. As a result, they drive away with what looks like a genuine key.
Ghost is built for exactly these attacks. After all, a relayed signal or a new key does not carry your PIN. So the car may open, but the engine stays blocked. For more on where cars are taken from, read our driveway car theft guide.
Can Thieves Get Past a Ghost Immobiliser?
We’ll be honest: no security device is unbeatable. However, Ghost makes a car far harder and slower to take. And thieves want quick, quiet wins. So here are the real weak spots, and how to cover them.
They Watch You Enter Your Code
If someone sees your button sequence, the PIN is no longer secret. So enter it discreetly, and change it if you think it was seen. Also, use service mode at garages instead of handing over your code.
They Find and Remove the Unit
Ghost has no LED and sends out no signal, so there is nothing obvious to find. Even so, a unit tucked in the first place a thief looks is a weak point. That’s why where it is hidden matters as much as the product itself.
They Don’t Drive It at All
Finally, Ghost stops the car being driven. It does not stop the car being lifted onto a truck, or parts being stripped. In short, that is the job of a tracker or an alarm, which is why we often fit them together.
So, Is a Ghost Immobiliser Worth It for Your Car?
It depends on your car, where you park it, and what your insurer asks for. Here is how we answer it for customers.
Relay theft and key programming are the main risks for these cars. So Ghost targets exactly that, and it is where we see the most value.
Think Range Rovers, Ford Rangers and Transits, BMW M cars and Audi RS models. Ghost stops the drive-away. Then a tracker helps find the car if it is lifted.
If your car is low risk and has no keyless system, the case is weaker. Even so, a Ghost still adds a PIN that a stolen key can’t get past.
Some insurers require a Thatcham S5 or S7 tracker on high-value cars. In that case, fit the tracker they ask for. Then add Ghost, which is TASSA approved rather than Thatcham, for real drive-away protection.
For example, the Audi RS4 above left with a Ghost, a Thinkware dash cam and Target Blu Eye. You can read the full Audi RS4 Ghost immobiliser build.
When Is a Ghost Immobiliser Not Worth It? The Downsides
Of course, there are trade-offs. First, you enter a code every time you drive, unless you choose the Ghost-III key-tag or app. Even so, it soon becomes part of starting the car.
Second, Ghost does not stop a break-in, a tow or parts theft. Also, it is a professional install, so it costs more than a steering lock. Then again, a steering lock does nothing against a car that starts with a cloned key.
Ghost Immobiliser or Tracker: Which Is Worth It for You?
They do different jobs. A Ghost stops the car being driven away. A Thatcham tracker helps the police find it if it is taken anyway, for example on a truck. Meanwhile, an alarm deals with forced entry. So for a high-value car, we usually suggest a Ghost and a tracker together.

Is a Ghost Immobiliser Worth It? Your Questions Answered
Is a Ghost immobiliser worth it on a keyless car?
Yes. Keyless cars are the main target for relay theft and key programming. A Ghost immobiliser asks for your PIN before the engine starts, so a relayed signal or a new key is not enough. That’s why we recommend it first for keyless cars, often alongside a tracker on high-value models.
Can thieves get past a Ghost immobiliser?
No device is unbeatable. However, Ghost has no LED or fob, and the car won’t drive without your PIN. Thieves can still lift a car onto a truck or steal parts. So for high-risk cars, we pair Ghost with a tracker, and we hide each unit carefully.
Is a Ghost immobiliser worth it if I already have a tracker?
Yes, for most cars. A tracker helps find the car after it has gone. A Ghost aims to stop it leaving in the first place. So the two work well together, and many of our customers in Cardiff fit both at the same time.
Is a Ghost immobiliser Thatcham approved?
No. Ghost is not a Thatcham product. Instead, Ghost is approved by TASSA, a separate vehicle security accreditation. Insurers treat TASSA approval in different ways, so check with yours before you fit. Also, if your insurer asks for a Thatcham tracker, you will still need one. Ghost can then go on top.
Does a Ghost immobiliser affect my car’s warranty?
No. We fit Ghost without cutting any factory wiring, so your manufacturer warranty is unaffected. It talks to the car through its own data network. Also, Ghost-III has a service and valet mode, so a garage can drive the car without knowing your PIN.
How much does a Ghost immobiliser cost to fit?
It depends on your car. The price varies with the make, model and year, and with whether you add the key-tag or app. So we quote for your car before booking. Call us on 029 2070 7275, or send your registration through our quote form.
In short, is a Ghost immobiliser worth it? For keyless and high-theft cars, we believe it is. So if you want an honest view on your own car, give us a ring and we will tell you straight.
